The Facebook group has the potential to be used as an LMS. It has pedagogical, social and technological affordances, which allow putting up announcements, sharing ideas and resources, and implementing online discussions. Using the Facebook group as an LMS, however, has certain constraints. It does not support other format files to be uploaded directly, and the discussion is not organized in a meaningful structure.
